You can create 1 depth buffer that is 1024x1024 and bind them to all 3 FBOs. Notice that the depth buffer is large enough for even the smaller textures like 64x64. 1 FBO or more Is it better to make 1 FBO and bind your texture to it each time you need to render to the texture?

WebOpenGL renders to framebuffers. By default OpenGL renders to screen, the default framebuffer that commonly contains a color and a depth buffer. This is great for many purposes where a pipeline consists of a single pass, a pass being a sequence of shaders. For instance a simple pass can have only a vertex and a fragment shader.
